Nokia E71 problem!

I needed to change the product code using NSS to update the firmware. The new product chose was O2 UK branded, (I didn't realize) and now Nokia Updater/Ovi doesn't give me an option to reinstall the firmware so I'm stuck with a branded phone.
I know realize I should have used 0567045 instead of the O2 one.

Is there anything I can do to get this O2 branding off? I have tried changing the product codes again and retrying to update but it just says no updates available and to exit (no mention of reinstalling).

Thanks for any help
